Converted to MONOGAME/OpenGL (from XNA/DirectX)
Locked to 64bit OS (wont work on win xp/vista anymore)
Removed ability to join with controller sticks/Dpad
Removed native Steam controller support (not worth all the extra work)
Added multi screen support
There has been a lot of hassle with getting the controllers work, if you get any issues - print screen the input Debug screen (see options) and post it.
